FOUS/HHN@ OR BUFFING WHEEL.

Specication of Letters Patent.

Patented April 10, 1906.

Application filed May 9, 1905. Serial No. 259.536.

a citizen of the United States, residing in the borough of Manhattan, city of New York, State of New York, have invented new and vuseful Improvements in Polishing or Bufng Wheels, of which the following is a specification.

My invention relates to buffng or olishing wheels, particularly to such Whee s which utilize librous scrap of various kinds, or wood, or leather, or layers ,or sections of materialsuch as cloth, canvas, wool, hair, and wood or pulp fiber-to receive the polishing material. It is customary to run such wheels at very high speeds and as a result when they i111- tially are or subsequently get out of a true balance they pound and shake and are in many ways objectionable.

The object of my invention is to provide an unbalanced wheel'with balancing-weights, so that it can be readily adjusted or altered when the wheel is, or becomes untrue through use, to locate such Weights so that they will not interfere with the attendant and so that they cannot become accidentally disengaged in use, and to arrange the balancing-weights so that theycan be readily removed and inserted without injuring the condition of the wheel.

Prior to my invention it has been customary to form in wheels of this kindholes into which plugs of lead were inserted forbalancing purposes. Wheels so constructed were not satisfactory for the reason that the lead plugs could not be readily altered after they were once inserted and were apt to become loose and dangerous at the high speed necessarily utilized. Y The boring ofsueh holes into wheels is further objectionable for the reason that such holes damage the wheels, restrict the amount of wear to which the wheels can be subjected, and ultimately when the number of holes become excessive spoils the wheels. It has also been customary to fasten lugs of lead to the Wheels for balancing purposes by means of nails or screws. This method is objectionable in that the pieces so fastened are liable to fly ol and hurt the attendant. They cannot be readily -adjusted and as they are usually located on the outer face of the wheel are very much in the way and are liable to injure the hands of the attendant.

//Referring to the accompanying drawings,

which form a part of this specification and show one form of my invention, Figure` 1 shows a vertical cross-section of the wheel on a diameter. Fig. 2. shows a side elevation of the` same with the polishing-pad removed. Fig. 3 is a side elevation of one of the elamp ing members looking from the-inner side and shows parts broken away in order to show the pockets in which the balancing-wei hts are carried. Fig. 4 shows a part of one o the -side members with the opening in position to receive the balancing-weights. Fig. 5 shows a similar view with the opening closed.

1V designates the shaft, on which is mounted side members 2 and 3, which I have shown identical in structure. However, it is obvious that vin some cases it will only be necessary to provide one oi these members with pockets to receive the balancing-wei hts. The side members clamp and holdin p ace pad 4, which is usually (but not necessarily) made of scrap or fibrous material of any suitable nature and in the usual manner and is covered by the cover 5. The side members may carry teeth (but these are not essentiall, which engage the pad and hold it in position.

7 7 designate nuts which clamp the side members in place.

8 designates the grooves, preferably annu lar, formed at or` near the peripheries of the side members and which open inwardly. Fitted into these grooves are annular rings 9, also grooved and opening inwardly. These rings have pockets 10formed at certain points along the groove on its inner side by the wallsi 12` and 13. `Holes 14 in theside members are arran ed so that they may coincide with holes 15, Formed inthe walls of the inner rin s. In order to turn the rings 9 so as to ma e the holes 14 and 15 coincide or se arate, I provide knobs or handles, prefera ly in screw form 17 which ass through slots 18 in the side lmembers an screw into the inner rings 9. By loosening these screws'the inner rings 9 can be moved so as to make the holes coincide, as in Fig. 4, in which position the balancing-weights, such as shot 16, can 4be readily inserted or removed, or the inner ring can be so turned as to close the holes, as shown in 5. While I have shown all of pockets arranged to open simultaneously, I am aware are re uired in the pocket or pockets substantia ly opposite the heavy side.

I have illustrated and described the Wheel With pockets arranged ninety degrees apart.

However, I do not desire to be limited to this particular number, as I may use a larger or greater number.

' spirit of.n1y invention. zo'

While I have shown and described a device with all of the details com lete, I am aware that in many Ways it can e altered by one skilled in the art Without departing from the i I believe myself to be the first to combine With the side pieces features of movable and changeable balancing to aglapt the side pieces to the required Wheels or to alteration of point of balance.

What I claim is- 1. In apolishing or builin Wheel, a, olishing-pad, op ositely-disposerI detachab e side members a apted to clamp said pad between their inner faces, one of said members being provided with detachable balancing-Weights, substantially as described.

2. In a polishing or bufiing Wheel, a olishingad, a detachable side member a apted to c amp one side of the same and provlded with an annular groove, and pockets spaced throughout the said groove for receiving balancing-Weights, substantially as described.

3. In a pol'lhing or buiiing Wheel, a olishingad, a detachable side member a apted to c amp one side of the same, and provided Withpockets for carrying balancing-Weights, 4o

substantially as described.

4. A polishing or bung Wheel comprising a detachable si e member havin an annular groove in one of the faces thereo balancingweights, and means for retaining said balanc- 4 5 ing-Wei hts lin said groove at a number of points t oughout its length, substantially as described.

5. A olishin or bufing Wheel comprising a detac able si e member having an annular 5o groove in one of the faces thereof, a ring fitting in said groove and ada ted to turn therein, pockets formed in sai r' and balancing-Weights in said pockets, lslllistantially as described. 5 5 6. A olishin or bufling Wheel comprising p a detac able si e member having an annular groove in one of the faces thereof, a series of connected pocketsv fitted in said groove and adapted to turn therein, and balancing- 6c Wei hts carried in the said pockets, substantialy as described.

7. A olishin or builing Wheel comprising a detac able sie member having an annular groove therein, a series of connected ockets 65 itted in said groove, balancing-Weigiits car- -ried in said pockets, openings in said side member and in said pockets, adapted to coincide With each other, for the purpose of removing or inserting balancing-Weights, sub- 7o stantially as described. A

In Witness whereof I have hereunto signed my name, this 3d day of May, `1905, in the presence of tWo Witnesses.
